I am looking for a strain of Klebsiella pneumoniae (nitrogen fixer) that is deleted for the nifH gene. I would like to use it in some com- plementation experiments with mutant nifH genes on a plasmid. Preferably, the deletion should not be polar onto nifD,K, or nifJ. Please reply to Tom Collet, Collet@MITWCCF. Thank you! Thomas
